I have seen a lot of machines without grass deflectors attached. While this can disperse clippings more evenly over the lawn, the risk of shooting debris is too great for my tastes. I will bungee cord up my deflector when in wide open spaces but never when near buildings/people/vehicles. The equipment at work is all rear discharge so this is not an issue, but the equipment that I have for my lawn care business is side discharge and I would never completely remove it. Just today, while going down the street, there was someone cutting a median with the deflector completely removed. With temperatures in the upper 80's I had my window rolled down and as I passed a chunk of branch was launched in my direction by the mower. What is the general consensus on keeping or removing a deflector?
